S. Stringari - Superfluid gases near absolute zero temperature

In this talk I will present a general overview of recent experimental and theoretical developments concerning the superfluid behavior of ultracold atomic gases. The transport properties and the propagation of sound, the nature of quantized vortices and the absence of viscosity will be explicitly discussed. Intriguing questions concern the connection between superfluidity and the phenomenon of Bose-Einstein Condensation and the role of dimensionality. The new perspectives opened by the availability of artificial magnetic fields will be also discussed.

Short Biographies

Lev Petronich Pitaevskii, educated at the Landau school in Moscow, is professor in Trento since 1989. His contributions spread to the theory of quantum mechanics, electrodynamics, low-temperature physics, plasma physics, and condensed matter physics. In his celebrated paper on quantized vortices he developed what is now called the Gross-Pitaevskii theory of Bose-Einstein condensates, which is one of the theories more systematically used to describe the physics of ultracold atomic gases nowadays. In 2008 he received the Landau Gold Medal in recognition of his research in modern theoretical physics, and for his contribution to the writing of new and previously unreleased update parts of the world-famous course in theoretical physics Landau-Lifshitz.

Sandro Stringari is professor in Trento since 1980. He is internationally known for his research in nuclear physics, cluster physics, low temperature physics and atom physics. More recently he became interested in Bose-Einstein condensation and superfluid effects in ultracold atomic gases, which are the topics of a renowned book published in 2003 for Oxford University Press together with Lev Pitaevskii. Since 2002 he is director of the Bose-Einstein condensation research center in Trento. Among his recognitions, the appointment to the European chair at the College de France in Paris in the academic year 2004/2005 and the conferment in 2011 of an advanced ERC grant with the project "Quantum Gases Beyond Equilibrium".
